Three major airports serve the Washington area: Washington Dulles International Airport (IAD), Ronald Reagan Washington National Airport (DCA), and Baltimore Washington International Airport (BWI). Reagan National Airport is the closest to Georgetown, and is the only one with metro access. Dulles Airport is the largest and has the most flights, especially for international travelers. BWI Airport is the farthest from DC (it is closer to Baltimore), but some airlines offer cheaper fares there.
All three of the airports have taxi service available at Ground Transportation and SuperShuttle, a door-to-door shared van-ride system. Check the SuperShuttle website (www.supershuttle.com) for fares and for the location of the SuperShuttle within the airport. The fare should be between $15-40 for the first passenger depending on your airport of arrival. Additional passengers are deeply discounted, so this is a good option if you are traveling in a group. No reservation is needed leaving from the airport. To take SuperShuttle back to the airport, reserve online or call 1 (800) BLUE-VAN (800-258-3826). Below you will find more airport-specific options.
